So besides the return pump that will be that last section of the sump, i'll also need to get another one for the skimmer, that's it? And can it be the same as the other one?
They can be different or the same. The skimmer pump needs to suck in air before the impeller so that the impeller can "grind" the bubbles.
Cheers! Mark
Thanks. I thought that i'd have to spend some good money on another pump, but for now that wont be necessary. As far as i know all skimmers have pumps included.
